| 15:57 | Fix a typo in a comment in a test case. No changes to code. (check-in: f501166de4 user: drh tags: trunk) | |
| 12:22 | Add a NEVER() around a branch in sqlite3ExprAffinity() that is designed to prevent an infinite loop, but which can now never be reached due to recent changes. (check-in: da0b794852 user: drh tags: trunk) | |

| 23:03 | Cleanup and commenting of the new DECIMAL extension code. No functional changes. (check-in: 5124481663 user: drh tags: trunk) | |
| 20:28 | Enhancements to the DECIMAL extension: (1) If the argument to decimal(X) is a floating point value (or an 8-byte blob), the floating point value is expanded into its exact decimal representation. (2) Function decimal_sci(X) works the same except it returns the result in scientific notation. (3) New function decimal_pow2(N) returns the full decimal expansion of the N-th integer power of 2. (check-in: 8baf8c10ae user: drh tags: trunk) | |
| 17:58 | Sync w/trunk (check-in: fe9aa2e9c1 user: larrybr tags: cli_extension) | |
| 17:48 | Fix harmless compiler warnings about unused function arguments. (check-in: 24927c1377 user: drh tags: trunk) | |
| 17:36 | Improve the range of floating-point numbers that can be handled as integers for numeric-to-text conversion. (check-in: 41580ba452 user: drh tags: trunk) | |
| 17:26 | Further refine the dtostr() testing function in the CLI so that it takes an optional second parameter which is the number of significant digits to display. (check-in: 2f9d4444aa user: drh tags: trunk) | |
| 16:48 | Change the (undocumented) dtostr() SQL function in the CLI so that it only shows the first 26 significant digits - 10 more digits than are available in a 64-bit double. (check-in: d758859f6a user: drh tags: trunk) | |
| 14:49 | Add the decimal_sci(X) function to the Decimal extension for showing a decimal value in scientific notation: +D.DDDDDe+DD (check-in: 61d4923913 user: drh tags: trunk) | |
| 12:14 | CLI enhancements to facilitate SQLite core testing: (1) Add built-in functions strtod() and dtostr() that convert text to floating point and back using C-library routines. (2) Do not disable all of ".testctrl" without --unsafe-testing, but only those subcommands of .testctrl that are actually dangerous. (check-in: 669996a8dd user: drh tags: trunk) | |

| 15:16 | Have the sqlite_stmt table buffer all data for the current scan within the xFilter method. (check-in: 84a91c255e user: dan tags: trunk) | |

| 20:26 | Fix generated columns so that they play well with upsert. See the forum post by "iffycan" for details. (check-in: fa9d93cf32 user: drh tags: trunk) | |
| 20:20 | Change the magic number used to identify the "excluded" pseudo-table in an UPSERT statement into a #define constant. (check-in: e96c2ac9ab user: drh tags: trunk) | |
| 20:09 | Document the dual-use of the P5 operand to the OP_MakeRecord opcode. (check-in: a73f80f22a user: drh tags: trunk) | |
| 19:58 | Passive checkpoints do not use the busy-handler. So, in order to minimize visible changes for legacy applications, do not enable blocking locks for passive checkpoints. (Closed-Leaf check-in: 9c2b4bdd03 user: dan tags: wal-setlk-changes) | |
| 18:30 | Change the name of IntegrityCk.mallocFailed to IntegrityCk.bOomFault to avoid confusion with the sqlite3 object field with the same name. (check-in: 87c7d96258 user: drh tags: trunk) | |
| 18:22 | Change things so that if SQLITE_ENABLE_SETLK_TIMEOUT is defined as 2 instead of 1, all blocking locks are taken for a single millisecond and the default busy-handler invoked as normal. (check-in: ac381e6eb3 user: dan tags: wal-setlk-changes) | |
| 17:52 | Add test script to verify busy-timeouts are working for SQLITE_ENABLE_SETLK_TIMEOUT builds. (check-in: ada43e7c49 user: dan tags: trunk) | |
| 16:30 | Do not run resetAccumulator() after a malloc failure. (check-in: 1b426603f0 user: drh tags: trunk) | |
| 13:33 | Fix another fts3 problem with processing corrupt records. (check-in: 6e0ffa2053 user: dan tags: trunk) | |
| 13:12 | Small performance improvement in the sqlite3_step() interface. (check-in: 61400ef9f1 user: drh tags: trunk) | |

| 23:01 | From sqlite3BtreeInsert(), bypass the btreeMoveto() routine for table inserts and go directly to sqlite3BtreeMovetoUnpacked(). (check-in: 53fe685d56 user: drh tags: trunk) | |
| 20:53 | Add a bypass path in sqlite3PagerWrite() for pages with the PGHDR_WRITEABLE bit set, for about a 1% performance increase. (check-in: ba425a6abb user: drh tags: trunk) | |
| 19:08 | Combine subjRequiresPage() and subjournalPage() into a single subjournalPageIfRequired() routine. (check-in: 3b65eb56c4 user: drh tags: trunk) | |
| 18:29 | Add the PGHDR_WRITEABLE bit for PgHdr.flags which is used to distinguish between pages that are on the dirty list and pages that are safe to modify. (check-in: 7c4ef7b7c8 user: drh tags: trunk) | |
| 18:14 | Fix over-length source code lines in pager.c. (check-in: 14de3d3926 user: drh tags: trunk) | |
| 15:41 | Fix minor problems in the ota demo application. (check-in: 6aaaec6e63 user: dan tags: trunk) | |
| 14:11 | Simplifications and performance improvement in pager_write(). (check-in: ab7aeeead3 user: drh tags: trunk) | |
| 04:21 | Add the new PGHDR_CLEAN bit to PgHdr.flags in pcache.c. This bit is always the opposite of PGHDR_DIRTY. Use the extra bit to avoid a comparison for a small performance boost. (check-in: 8619fc346d user: drh tags: trunk) | |
| 03:28 | Very small size reduction and performance increase in sqlite3BitvecTest(). (check-in: 9b3a7281bd user: drh tags: trunk) | |
| 00:52 | Move an assert() and testcase() into their correct position within getAndInitPage(). (check-in: 18115164e1 user: drh tags: trunk) | |
| 00:21 | Use tail recursion in pcache1Unpin() to get a small size reduction and speed improvement. (check-in: fde70472ae user: drh tags: trunk) | |
